IMPROVEMENT IN WIRE FABRICS.

Specification forming part of Letters Patent No. 169,986, dated November16, 1875; application illed l May 2-s, 1875.

.To all whom. it may concern:- V

my fabric. Fig. 3 is a view of my'warp-wire.-

This invention has relation to improvements in the manufacture of wovenwire-cloths,which are especially well adapted for use in connection withwire mattresses; and the nature of lthe invention consists in a numberof spiral coils laid side by side, whichare formed into a web or fabricby means of traverse-wires, which are corrugated, whereby each spiral isendowed with an independent action, greatly increasing the elasticityvand durability ofthe fabric, as will be fully understood from thefollowing description.

In the annexed drawings, A designates the warp-wires of my improvedfabric, which are formed of preferably steel wires twisted\to formspiral coils, which coils are various sizes, according to the degree ofcloseness required for the web. These spirals are placed side by,

side in sufficient numbers to produce a desired width of fabric, and areconnected by means of weft or traverse wires B, which extend directlyacross the warp from selvage to selvage, and are interwoven, the onefrom above and the other from below, with the spirals, sothat other.

each of the warp-wires shall be includedin a loop formed by wires Bcrossing each other,. as shown. -Wires B are rigidly Secured at each endto the selvage war1: -wiresA, and they thus hold the warp or spiralwires A A in close contact with each other, while they are permitted tohave a slight endwise play, which allows them torhave an actionindependent of each By this means the fabric vis endowed with a verygreat degree of elasticity.

rlhese traverse-wires may be arranged at any distance apart which I mayelect, and the loop formed by their intersecting eachother wheninterwoven with the warp may be made larger or Smaller, according to thepurpose to which the fabric is designed to be applied.

I am aware that a springbed-bottom composed of longitudinal andtransverse spiral springs, interlaced asshown in Letters Patent grantedto Morris Kohn, dated November 21, 1871, numbered 121,111., hasheretofore been employed; |and I, therefore, lay no claim to suchinvention, broadly.

What I claim as new, and desire to secure A wire fabric consisting ofthe spirallycoiled warp-wires A, connectedV together by the bent wiresB, interlaced with each' other at intervals between said warpwires.substantially as and for the purpose set forth.

In testimony that I claim the above I have .hereunto subscribed my namein the presence of two witnesses.
